PC Moment: Perfect spring weather greeted Stella McCartney as she joined the most fashionable admirers for an afternoon tea party celebrating her boutique, which opened on October 3rd, in Houston’s River Oaks District. The crowd sipped champagne, nibbled on tea sandwiches and enjoyed handbag-decorated sugar cookies and cakes by For Heavens Cakes. All of this while chatting up the designer and shopping her spring-summer collection. A portion of the evening’s proceeds were donated back to the Menil Collection’s Contemporaries Fund.
